Secure NTP servers

THE INSTRUCTIONS IN THIS ARTICLE WORK IN AMP 4.4 AND OLDER, BUT ARE NOT RECOMMENDED FOR VERSIONS NEWER THAN 4.4.

Configuring AMP's NTP client to sync to your secure NTP servers is very easy. I'll tell you how to configure it, and then I'll describe the "gotcha" that you should be aware of.

To tell NTP to use a key you just save the key somewhere on the AMP and add one line to the /etc/ntp.conf file:

keys /absolute/path/to/key_file

Then just restart AMP to make the changes take effect:

# disable_amp; enable_amp

The gotcha: If you go to the AMP Setup -> Network page on AMP's web interface and make a change to the NTP servers' addresses, AMP will delete the 'keys' setting from ntp.conf. So once you do this you should remember not to edit NTP server stuff from our web interface.Configuring AMP's NTP client to sync to your secure NTP servers is very easy.
